I've tried it at least 10 times I use the one that's here http://paintdotnet.12.forumer.com/viewtopic.php?t=2911

I saved it onto my desktop. When I open it there are just a whole bunch of letters,numbers,symbols... When I right click it and go to 'properties' it says the type of file is a 'ZIP File (.zip) and that it opens with 'wordPad'. I used the DLL that's in the 'Plugins' section of these forums.

I downloaded the plug-in and put it in the effects folder and unblocked it. I still can't find the effect in p.net. All I have in effects>Distort is: bulge, polar inversion, tile reflection and twist. That's where the 'water' should be right? I downloaded the 'portrait-effect' and everything went ok. So what am I doing wrong with this one? :? Could anyone please be so kind and help me? Consider I'm really new to this. ETA: I just checked in the effects folder and under Type it says ZIP File instead of 'Application extension'. I read about having to extract, but how do I do that? When I had it on my desktop ,after downloading,and rightclicked it there was no 'extract',only 'open'... I also want to mention I have 'Windows Vista'.Maybe that makes a difference.
